On 11 September, I was living in Greenwich Village, New York; my children learned to tell south from north by looking at the World Trade Center.

If the perpetrators of the World Trade Center plane crashes had a nuclear weapon, there's no doubt in my mind but that they would've detonated it in New York.

On September 11, the murders of World Trade Center employees and visitors took the lives of numerous nationalities, ethnic groups and religious followers.

When I show up in New York, and I look at the skyline, it's like showing up in a mountain range. My gaze goes toward the most impressive-looking climb. It's always gone to the top of the World Trade Center.

Every year, I am conscious of the anniversary of my 1974 World Trade Center walk.

Skill is successfully walking a tightrope between the twin towers of New York's World Trade Center. Intelligence is not trying.
